Question

Find the area of triangle formed by
the vertices (-2,3), (-3,-4) and (4,-3)​

Answer 1

Answer:

The area formed by triangle using above points is 1152sq units

Formula:

half of [y₁ (x₂ - x₃) + y₂ (x₃ - x₁) + y₃ (x₁ - x₂)]sq

Answer 2

Answer:

24

Step-by-step explanation:

Area = (1/2) |x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂) |

= (1/2) |(-2)(-4+3) + (-3)(-3-3) + (4)(3+4) |

= (1/2) |(-2)(-1) - 3(-6) + 4(7) |

= (1/2) |2 + 18 + 28 |

= (1/2) |48 |

= 24
